VALVE.

SPECIFICATION forming part of Letters Patent No. 556,312, dated March10, 1896.

Application filed June 27,1895. Serial No. 554,238. (No model.) I

T at whom it may concern.-

Be it known that I, CHRISTOPHER GULL- MANN, a citizen of the UnitedStates, residing at New York, in the co unty and State of New York, haveinvented new and useful Improvements in Valves, of which the followin isa specification.

This invention relates to a valve or faucet which during the openingmovement is loosened or lifted from its seat and during the closingmovement is pressed to the seat so as to effect firm closure; and theinvention resides in the novel features of construction set forth in thefollowing specification and claims and illustrated in the accompanyingdrawings, in which Figure 1 is a sectional elevation of the valve openand showing a manner of use. Fig. 2 is a sectional elevation of thevalve closed. Fig. 3 is a section along line a; m, Fig. 2. Fig. 4 isaview of apressure-chamber sectioned along line y y, Fig. 3. Fig. 5 is asec tion along line .2 2, Fig. 3. Fig. 6 shows a modification.

In the drawings the valve is shown applied to use in connection with apump-chamber 1, also known as a pulsator and familiar in such works asdredging; but of course the use of the valve need not be limited to suchapparatus. The inlet 2 causes matter to be discharged into chamber 1when a vacuum has been formed in the latter, and the outlet takes offthe matter discharged by pressure in the chamber 1, as known.

The inlet 2 is shown with a valve-chamber athaving a valve-actuatingshaft 5 from which extend arms 6 carrying the valve-lid part or section7, to which is connected the lid part or section 8 by pin-and-slotconnection 9 and 10 to allow the two lid parts 8 and 9 certain play ormotion with respect to one another.

The lid part 8 has a nose or incline 11 extending into a hole or recess12 in lid part 7. The closing movement of shaft 5 carrying the valve-lid7 and 8 toward the stop 13 and the lid portion 8 being arrested by saidstop while the lid portion 7 continues somewhat farther in the closingmovement, the action or press ure of lid portion 7 riding along thewedge or incline 11 will press the lid portion 8 firmly to the seat toeffect tight closure. A return or opening movement of shaft 5 and lidpor- 17 the blades 14 are moved to give a closing swing or turn to shaft5, while an exhaust through ports 16 and pressure through ports 17 willcause the valve to be opened. The pressure-chamber is suitably dividedinto compartments by partitions 18. The pressure entry and exhaustthrough ports 16 and 17, as known, is effected by suitable valves 19worked by hand or by suitable well-kn0wn mechanism.

To prevent slamming of the blades 14: a dash-chamber 20 is provided. Theportion of shaft 5 which projects into the dash-chamber is provided withblades 21, Fig. 5, and as the shaft rocks the blades 21 are arrested bystriking soft pads or springs 22 suitably secured in the dash-chamber.Other forms of dash-chamber or dashpot might answer, as by fillingchamber 20 with fluid, but the construction shown is simple.

The outlet 3 may have a like valve as inlet 2, but a simple lid-valve orother valve may be made to answer for outlet In place of operating shaft5 by pressurewings 14., any other actuatoras, for example, a handle orlever 14may be taken as an equivalent for actuating said shaft.

The vacuum and pressure in pump-chamber 1 can be produced, as wellknown, by allowing steam to enter the chamber and then condensing thesteam by a suitable dash or jet of water, thus causing a vacuum, whilepressure in chamber 1 is readily created by allowing water or steampressure to enter the chamber 1 as required. For controlling the waterand steam inlets into chamber 1, valves as just described, actuated by ahandle, as

lid and an actuating-shaft for the lid, eo1nbined with apressure-chan1ber, actuatingwings in said pressure-chamber secured tosaid shaft, a dash-chamber, and dash-wings in the dash-chambersecured tothe shaft suhstantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
